Abstract: The retracement laneway of 3506 final working face in Matigou Coal Mine is affected by the mining disturbance of the adjacent 3505 working face, and serious deformations such as roof subsidence, inner bulge of the gang, floor uplift and tunnel section reduction have occurred successively, which seriously affect the safe and efficient retraction of production equipment in 3505 working face. In order to effectively control the deformation of the surrounding rock, based on the interaction mechanics model between the rockbolt and the surrounding rock, an inversion analysis was carried out on the deformation range of the surrounding rock anchored in the retracement laneway. On this basis, a targeted secondary anchor-injection joint reinforcement scheme was proposed, and the stability of surrounding rock after secondary reinforcement was monitored on site. The results show that the deformations such as roof subsidence, two gangs movement and floor uplift are effectively controlled after the secondary anchor-injection joint reinforcement of the retracement laneway.
